CabKing screw-back discs spin on to the cabber's shaft end and provide a backing for polishing pads, such as a felt polishing pad.
Spin-on discs are 6-inch diameter and made of 1/4' thick plastic composite material. They come with a 1/4-20 thread on the backside to easily screw into the right shaft of the 6-inch CabKing cabbing machine and the 8-inch CabKing cabbing machine. You can also use them on other cabbing machine brands that accept a 1/4'-20 thread. One 6-inch sponge pad is included to provide a cushion ideal for polishing cabochons!
